Mount Wilson Observatory Tour

(5 hours)

$69 per person – minimum 30 participants

Sat. July 14 -10:00-15:00 (lunch box included)

Located on the summit of Mount Wilson above Pasadena at an altitude of 5715 feet, the Observatory is visible from much of the Los Angeles area. Home to the historic Hooker 100-inch telescope, Mount Wilson is the most scientifically productive astronomical observatory in history and was the preeminent facility in the world in both stellar and solar studies during the first half of the twentieth century. Modern instrumentation has enabled both the original superb telescopes and more-recently-built facilities here to continue Mount Wilson’s pioneering heritage in new fields of study. 

Price includes: Deluxe coach transportation, docent led tour of the observatory and the grounds (approx. 2 hours), boxed lunch, applicable taxes & service charges.

Note: this tour involves walking at elevation and on uneven surfaces.

All Aboard! Tour of SOFIA at COSPAR on Sunday, July 22, 2018

(8 hours)


Sund. July 22

The Stratospheric Observatory for Infrared Astronomy (SOFIA) will be hosting a tour of the observatory and its facilities at NASA Armstrong Flight Research Center, with participants guided throughout the tour by SOFIA scientists!

SOFIA consists of a Boeing 747SP aircraft carrying a telescope with an effective diameter of 2.5 meters to altitudes between 12 and 14 km (39,000 to 45,000 ft). At those altitudes, SOFIA is above more than 99 percent of Earth’s atmospheric water vapor to yield an 80 percent average atmospheric transmission. The telescope is mounted in an open cavity in the aft section of the aircraft and views the sky through a port-side door. SOFIA was designed to allow for an evolving science instrument suite, making it one of the premier facilities for astronomical observations at infrared wavelengths. The present instrument suite enables imaging, spectroscopy, and polarimetry observations from 0.3–612 μm and additional capabilities are currently in development. SOFIA is a joint project of NASA and the DLR (German Aerospace Center) designed to provide a world-class, versatile observatory for the next two decades.

The tour is free, with transportation to and from the COSPAR conference venue, and lunch will be provided. The technical nature of the tour is intended for COSPAR participants, but those not attending the conference may still register for the waitlist. The chance to participate in a tour of the observatory guided by SOFIA scientists is popular and space is extremely limited, so register early!
